HEEL-BUILDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 760,768, dated May 24, 1904.

v Application filed August 25, 1903- Serial No. 170,745. (No model.)

T0 on whom it may concern:

- Be it known that I, WILLIAM WOLFE, a citizen of the United States, residing at Batavia, in'the county of Clermont and State of Ohio, have invented a new and useful Heel-Building Machine, of which the following is a specification. j 1

' This invention relates to improvements in machines of that class employed in the manufacture of heel-blanks, and has for its principal object to provide means for properly ad'- -justing a number of assembled taps ,or lifts and unite the same by a simple fastening means in the form of a heel-blank.

A further object of the invention is to provide novel mechanism of the single-actuatingmovernent type, wherein the parts assume inoperative position immediately after each operative movement and remain in inoperative position until again connected to the actuating mechanism.

With these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter de scribed, illustrated in the accompanyingdrawings, and particularly pointed out in the appended claims, it being understoodthat various changes in the form, proportions, size, and minor details of the structure may be made Without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is aside elevation of the heel-building machine constructed in accordance with the invention. Fig. 2 is a front elevation of the same. Fig. 3 is a plan view, partly in section, on the line 33 of Fig. 1.- Fig. 4 is a detail perspective view of one of the tap or lift adjusting blocks. Fig. 5 is a transverse sectional elevation of a slightly-modified construction of nail-block. Fig. 6 is a detail view of a portion of the mechanism for imparting intermittent rotative The frame 1 of the machine is mounted on a suitable bed or table at a convenient height above the floor, and includes a base member 2 and a vertical arm 3. The base is provided with a pair of horizontally-disposed guides 4: for the reception of a slide 5, by which the assembled taps or lifts are moved to position under the nail-driving mechanism, said slide being provided near one end with a gage 6, against which the lifts are piled until they are level with the top of the gage. The slide is connected by a helical spring 7 tea bellcrank lever 8, pivotally mounted on a stud at one side of the spindle 3 and receiving motion in the manner hereinafter described. 7

At'opposite sides of thebase-plate are arrangedblocks 9, 10, and 11. These blocks serve as supports for a plurality of adjustable plates 12, each of which is provided witha slot 13 for the passage of a locking-bolt 14.,

lifts, so that each will engage its proper tap or lift and move the whole to a predetermined position with respect to the remaining portion of the heel. The plates carried by the blocks 9 and 10 extend in a direction transverse of the base and are arranged directly opposite each other, while the plates carried by the block 11 are slighly curved, in order that their operating faces or ends may engage the rear face of the heel, the mounting of these plates being such as not to interfere with free move-. ment of the blank-carrying slide 5.

At one side of the base is a vertically-disposed rod 15, carrying a perforated nail-block l6, that'may be-adjusted to a position immediately above the several tap or lift engaging plates and locked in such position by means of a set-screw 17 and said block may be adjusted vertically in accordance with the height of the heels to be made. This block is pro- Vided with an approximately central opening 18, through which nails are fed singly from the chute 19, the nails being held. from falling through the opening by means of a small of a vertically-movable bar 23. The lower end of this bar is threaded for the reception of a screw 24, that is provided with a milled coliar 25, that may be turned in order to ad just the position of the screw, and to the lower end of the screw is secured a chuck 26, carrying a driver-rod 27, which is reciprocated in order to drive the nails through the nailblock to the heel-blank.

The frame of the machine is provided with bearings for the reception of a shaft 30, to the inner end of which is secured a combined cam and crank disk 31, having a wrist-pin 32, that extends through a horizontally-disposed slot 33 in a cross-head carried by or forming a part of the bar 23, the length of the slot being at least equal to the throw of the crankpin. This mechanism serves to impart driving movement to the driver-rod.

On that side of the crank-disk opposite the wrist-pin is a lug or roller 34, that is adapted to make contact with a vertically-movable cam-bar 35, guided in a cross-bar 36 at the top of the frame, the bar being held in position by a headed pin or screw extending through a vertical slot in said bar.

At the top of the frame is a rearwardly-extending arm 38, carrying a vertical stud 39, that forms the center of rotation of a nailfceding disk 40. This disk is provided with an annular series of nail-receiving pockets 41, to which nails are successively supplied in any suitable manner, and these pockets are successively brought into vertical alinement with the upper end of the nail-chute 19, so that single nails may fall through the chute to the opening 18 of the nail-block, preliminary discharge of the nails being prevented by contact with the arm or a suitable guard 41' on which the nails rest up to the time the chute is reached. The disk is provided with a number of cam-teeth 43, corresponding to the number of pockets, and withthese teeth engages the cam-bar 35, the bar being moved upward once at each operation of the machine and serving to impart angular movement to the disk to the extent of a single tooth.v

At the upper end of the cam-bar 35 is a cam 45, that serves to engage the cam-teeth 43 at each upward movement of the cam-bar, and

at each operation an angular movement is imparted to the disk to an extent equal to the distance between two of the cam teeth, so that the nail-receiving pockets are successively presented in alinement with the nail-chute. The limit of effective movement of this cam is fixed by a guard 46, arranged at the upper end of the cam-bar, and in operation the upward movement of the cam-bar serves to impart to the disk a moven'ient suiiicient to feed a single nail to the chute at each operation. The guard member is provided with a slot 47, through which extends a locking-screw 48 for locking the guard in any position to which it may be adjusted.

The combined crank and cam-disk has an irregular periphery, with which engages a roller 49, arranged at the inner end of a bellcrank lever 50, that is pivoted to an arm or bracket 51, extending rearwardly from the standard 3. The opposite arm of the bellcrank lever is connected by a link to the lever 8 and the two levers are so proportioned that when operated upon by the cam-surface of the disk movement will be imparted to the slide 5 and force the same in the direction of the heel-shaping plates 12, the connectingspring between the lever 8 and the slide being such as to yieldably hold the rear edges of the heel-forming taps or lifts against the real adjusting-plates and thus properly position the several lifts, while at the proper time the plate 14 will be withdrawn and allow the entering end of the nail to rest against the up permost tap or lift in position to be driven home by the rod 24. This operation of the mechanism may be somewhat modified, as shown in Fig. 5, whereinthe nail-block slide 14 is shown in the form of a rod or plate having a tapering end portion against which the pointed end of the nail rests, the relation be tween the rod or plate and the nail being such that when downward movement is imparted to the nail by the driver-rod the nail will be forced past the plate and into the heel-blank.

On the shaft 30 is arranged a clutch, which may be of any ordinary construction and which forms no part of the present invention, the clutch-operating mechanism being connected to a suitable pedal-lever and being preferably arranged in such manner that a single portion of the pedal-lever will impart a single rotative movement to the shaft.

In the operation of the mechanism the lifts or blanks are assembled on the slide 5 to a height determined by the gage 6, and on the connection of the shaft to the actuating mechanism the slide is drawn inward or in the direction of the nailing mechanism until the taps or lifts engage the adjusting or shaping plates and the lifts are moved to proper position. The slide 19 is then withdrawn, allow+ ing a previously-fed nail to descend until its entering end rests on the uppermost lift,
